BAG.

Specification of Letters Patent.

Patented Aug. 28, 1917.

To all whom it may concern:

Be it known that 1, JAMES WILLIAM LEARY, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Bags, ofwhich the following is a specification.

My present invention pertains to an improved bag of the square,satchel-bottom t e.

The object of the invention is to produce a bag of the above type, witha liner of moisture-repellent material, and having no projecting tabs orears upon the exterior of the bag, whether the bag be in its collapsedor set-up condition.

The bag and the blanks from which it is produced are disclosed in theannexed drawmgs, wherein:

Figure 1 is a plan view of the outer or bag-blank with the inner orliner-blank imposed thereon;

Fig. 2 a like view after the first 0nd folds have been made; I

Fig. 3 a similar view, wherein of the blank are inturned; I

Fig. 4 a perspective view illustratmg the manner in which the final foldis made;

Fig. 5 a like view of the two blanlm;

Fig. 6 a vertical section of the bag its collapsed condition;

Fig. 7 a similar view of the expanded or set-up bag;

Fig. 8 a perspective view of the e anded bag viewing the bottom thereof,with a portion broken away; and

Fig. 9 a vertical sectional view through the bottom and one side of thebag.

While both the exterior and llner members contribute to the strength ofthe bag and enter directly into its make-up, the exterior member, forthe sake of clearness in description, will be hereinafter referred to asthe ba -blank and the other as the liner, or liner-b ank.

The bag-blank is produced from a sheet of suitable material, andcomprises two sections 1 and 2, both substantially rectangular in formand in the present instance substantially oblong, though the lower endof 1 is cut out while the upper end of 2 is peaked so as to produce aprojecting edge at the top of the bag, see .Fig. 6, to facilitate themanipulation of the bag in the opening of the and secthe edges .tion ofthe bag) same. The size of the bag to be produced will, of course,determine the relative width 'andlength of the sections 1 and 2.

The liner blank comprises two sections,- 3 and 4, of substantially thesame form as the bag blank, section 3 being vnarrower than section 1,which it overlies, and section 4. being wider than the underlyingsection 2.

-The bag and liner blanks will be scored lengthwise upon the lines(dot-and-dash) 5 and 6,and preferably scored upon the converging lines7, 7 and 8, 8, lines 7, 7, extending downwardly and outwardly from thejunction of line 5 (or 6 as the case may be) and the initial foldingline 9, coinciding with the second folding line 10 and score lines 8.Said latter lines extend downwardly and inwardly and merge into scoreline 5 (or 6) and also the fourth lineof fold 11. i F

.Paste or other suitable adhesive, shown in stipple, will be applied tothe triangular .spaces 12, formed between said scoring lines 7 and 8,the margins of the bag blank and the fold lines) and 11. Theoppositelydisposed edges or marginal portions of the sections 2 and 4:,are designed to be turned inwardly, as shown in Fig. 3, the lines offold (being the third operation in the formabeing designated by 14,

and coincident with the longitudinal edges.

of section 1.

.Adhesive, shown in stipple, will also be applied to the exposed orouter faces of said inturned portions, or flaps, 13.

The bags are designed to be produced by machinery, and the steps offormation will be as follows: 7 The scored liner blank will be imposedon the scored bag blank (or they may be scored after placement) andsections 1 and 3 turned or folded upwardly on the initial folding line9, and then folded back on line 10, or said folds may be simultaneouslyformed, adhesive being applied to the spaces 12, if it be desired toseal the; inturned tabs 15, Figs. 6, 7, 8 and 9. The blanks are then inthe position shown in Fig. 2 and the side flaps, 13, are turned inwardlyand the lower portions of the sections 1 and 3 ofthe bag and linerblanks are folded upwardly on the folding line 11 and brought intocontact with said flaps 13, to which adhesive has been applied.

plied to cause proper adhesion, and heat may be employed if desired tospeed the operation.

The bags when completed and collapsed will be of the form shown in Fig.6., and when opened, or set-up, will appear as in Figs. 7 and 8, thetabs or ears 15 naturally forming and extending upwardly from the bottomof the bag adjacent the sides, as is clearly shown. While the formationand folding of the parts tends to hold the liner or inner bag inposition with the outer bag, the use of adhesive on the spaces 12 causesa positive retention of the liner or inner bag in place.

Paper of a quality to meet the require-' ments of the purpose for whichthe bag is to be used will be employed in producing the blanks.

I have referred to the score lines 5 and 6, and scoring upon lines 7, 7and 8, 8. Such scoring is not absolutely essential to the formation ofthe bag though its presence enables the bag to be opened or squared upwith greater facility.

Having thus'described my invention, what I claim is:

1. A square-bottomed, double-walled bag formed from an outer blankhaving a narrow member and a broad member, produced from a single pieceof paper; and an inner blank havilig similar members, the narrow memberbeing narrower than the corresponding-member of the outer blank, whilethe wider member is wider than the corresponding broad member of theouter blank, the narrow members being of greater length than the broadmembers, the sides of. the wider portions of the superposed blanks beingturned inwardly and having the outer faces thereof secured to the edgesof the narrow members which are turned upwardly thereover, the narrowermembers adjacent the point of junction with the wider members, beingfolded to form a satchel-bottom and produce ears which extend inwardlyfrom the bottom adjacent the sides of the completed bag, when the bag isset up or squared.

2. A square-bottomed bag formed from an outer blank of suitable paper,and a lining blank of moisture-repellent paper, each blank comprising abroad member and a narrow member, the broad member of the lining blankbeing broader than the corresponding member of the outer blank, and thenarrow member of the lining blank being narrower than the correspondingmember of the outer blank, and the narrow members being longer than .thebroad members,-

said blanks having alined scoring lines extending throughout the lengththereof, spaced respectively a slight distance from the edges of thenarrow member of the lining blank, said narrow members being folded uponthemselves adjacent the wider members to produce a folded bottom, theedges of said narrow members bemg secured to the outer faces of theinturned edges or flaps of the wider members when the narrower membersare turned upwardly thereover.

3. A square-bottomed bag formed from an outer blank of suitable paper,and a lining blank of moisturerepellent paper, each blank comprising awide and a narrow member, the narrower member of the lining blank beingnarrower and the wide member wider than the corresponding memb rs of theouter blank, said blanks having ined scoring lines extending. lengthwisethereof spaced respectively. a slight distance in-' wardly from theedges of the narrow member of the lining blank, the narrow membersadjacent the wide members being provided with outwardly-convergingscoring lines at each side extending from the longitudinal scoring linesaforesaid, said narrowimembers of the blanks adjacent the wider "membersbeing first folded over the wider members, then backward uponthemselves, and then upwardly over the fold thus formed, and over thewide members, being secured at their edges to the outer faces of theinturned flaps formed along the edges of the wider members. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
